Laboratory Techniques and Measurements Lab 1
The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know, identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions, measurements, and weights to then calculate using algebraic formula.
Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the…show more content…

This lab is all about measurements and recording them properly. The lab first introduces to use the measurement of centimeters, millimeters, and meters to measure different household objects in our everyday life. We were given the task to use the provided ruler and measure a CD, key, spoon, and a fork in centimeters and then convert our findings to give us the appropriate units of millimeters and meters for each object required in the exercise.

Lab 1 also teaches us the importance of molecular weight of a substance and how to use that to find the amount of moles of that substance in a solution. For example; in exercise 3 we were asked to weigh 8 grams of sugar and then calculate how many moles of sugar it really was. Using the molecular weight of sugar (C = 12.01 grams/mol, H = 1.008 grams/mole, O = 15.00 grams/mole). We were then able to use this molecular mass of the sugar that we then had to use to calculate and determine the molarity of the sugar

Lab One: Laboratory Techniques and Measurements
Abstract
The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data…

General Chemistry 1
Lab 1: Laboratory Techniques and Measurements
Purpose: The purpose of this lab is to ensure that students are able to understand how to conduct measurements of length, mass, temperature, density and volume using different measuring devices. Students will also learn how to dilute substances by using simple algebra.
Procedure:
1. Prepare a data table similar to Data Table 1 shown below.
2. Choose any three objects that are shorter than the metric ruler to measure…

Laboratory Techniques and Measurements
Purpose
The purpose of this experiment is to determine mass, length, temperature, volume, and density of objects and liquids using common measuring devices and algebraic formulas. The metric system, the most common set of measurements used in science, which includes meters, liters, Celsius, and grams will be used.
Procedure
The following items were used within the experiment:
(1) Metric ruler with centimeter (cm) and millimeter (mm), (1) table…

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing…

Title: Laboratory Techniques & Measurements
Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.
Procedure: I used a ruler, thermometer, and scale to take measurements. I used a graduated cylinder, short step pipet, scale, and ruler to determine volume and density. I used a…

Observations of Chemical Changes
Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.
Procedure: Measure the…

Lab #3
